Which statement is true for the graph of y = -x^2-5 ?
the graph is v-shaped, facing upward in quadrants i and ii only
the graph is v-shaped, facing downward in quadrants iii and iv only
the graph is v-shaped, facing upward and is in all 4 quadrants
the graph is u-shaped, facing upward in quadrants i and ii only
the graph is u-shaped, facing downward in quadrants iii and iv only
the graph is u-shaped, facing upward and is in all 4 quadrants

The graph is U-shaped, facing downward in Quadrants III and IV only

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
